DTC C1057-14: Rear Axle Piston Pressure Regulating Valve - Circuit short to ground or open: Action
- Refer to the appropriate system wiring diagram and check the dynamic response rear actuator piston-side pressure regulating valve coil circuit, harness and connectors for short circuit to ground, short circuit to another circuit, open circuit, high resistance. Repair circuit as required, clear the DTCs and retest
- Refer to the appropriate system wiring diagram and check the resistance of the dynamic response rear actuator piston-side pressure regulating valve coil circuit (nominal value should be 5.1 ohms). Repair circuit as required, clear the DTCs and retest
- If the fault persists, install a new dynamic response valve block as required and clear adaptive data. Clear the DTCs and retest
